We look at the division of 47558979 by 73 
The aim is to understand the frequency of 73 in 47558979.

Going ahead to step 1:
73 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 73

Going ahead to step 2:
If we divide 47 by 73, we get 0 and a remainder of 47.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 47, we get 47.
Take the next digit (5) from the dividend and append it to 47, then repeat: 475 / 73

On to step 3:
If we divide 475 by 73, we get 6 and a remainder of 37.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 438 away from 475, we end up with 37.
Take the next digit (5) from the dividend and append it to 37, then repeat: 375 / 73

Going ahead to step 4:
73 can be fit into 375 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Subtracting 365 from 375 leaves us with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 73

On to step 5:
If we divide 108 by 73, we get 1 and a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 651.0
Deduct 73 from 108 and we're left with 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 73

Going ahead to step 6:
The number 73 fits into 359 4 times, leaving a remainder of 67.
The number 4 becomes the next digit in our result. 
Result so far: 6514.0
The remainder is 67 after subtracting 292 from 359.
Fetch the next digit (7) from the dividend, attach it to 67 and continue: 677 / 73

Going ahead to step 7:
If we divide 677 by 73, we get 9 and a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 65149.0
If we take 657 away from 677, we end up with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 73

Going ahead to step 8:
If we divide 209 by 73, we get 2 and a remainder of 63.
The next digit of our result is 2. 
Result so far: 651492.0
The remainder is 63 after subtracting 146 from 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 9:
73 can be fit into 630 8 times, resulting in a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 651492.8
The remainder is 46 after subtracting 584 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 10:
If we divide 460 by 73, we get 6 and a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 651492.86
Deduct 438 from 460 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 11:
When dividing 220 by 73, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 651492.863
If we subtract 219 from 220, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 12:
10 divided by 73 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 651492.863
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
When dividing 100 by 73, we get 1 with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 651492.86301
Subtracting 73 from 100 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 14:
73 goes into 270 3 times with a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 651492.863013
The remainder is 51 after subtracting 219 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 15:
510 divided by 73 is 6 with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 651492.8630136
Subtract 438 from 510 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 16:
720 divided by 73 is 9 with a remainder of 63.
The next digit of our result is 9. 
Result so far: 651492.86301369
If we take 657 away from 720, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The quotient of the division is 651492.86301369, and the remainder is 6.3e-08.
